Then I consider that I live in cold climate with long and dark winters. I wonder where is the truly grid scale energy storage to go over winter...

Okay, currently it is Norway and it kinda works, but that really doesn't look too good just now...

Well Norway should probably not do solar (except marginal, e.g. instead of traditional roof tiles solar roofs instead). But Norway had plenty of hydro and thermal options, even wind should work well in the more southern areas.

Thermal? Where and what would that be?
